Guest SeanT Posted March 18, 2006 Hi Guys, OK the car keeps idling about 1700-2k so I was reading up about the AFMs on here and there was people saying that they rotated the AFM so the plug pointed down, I moved it slightly and idle did drop and when it returned to its original poition the idle went up again.....am i going to cause any issues by loosing off the AFM and moving it properly and also should I retrack it at the sametime?? has anyone else had this on there MI16??

Guest SeanT Posted March 19, 2006 Ok I rotated the afm and the revs have dropped to a constant 1500k which I know is to high but its an improvement, maybe Ill try the re tracking during the week.

jackherer 543 Posted March 19, 2006 rotating the AFM shouldn't affect the idle really. I've had a similar problem and it was caused by a split on the hose that connects the AFM to the throttle body (where the idle control valve or breather hose connects) so you may have the same problem and you've moved the hose while rotating the AFM. btw, its not possible to retrack an Mi16 AFM in the same way as an 8v one.

j_turnell 137 3 Cars Posted March 19, 2006 (edited) Sounds like an air leak do a search, the angle of the afm makes bugger all difference. Edited March 19, 2006 by j_turnell Share this post Link to post Share on other sites
Guest SeanT Posted March 20, 2006 Cheers I will check for leaks at the weekend, if it is wheres a good place to get a replacement??....also just to note when I started this morning from cold, the cold start rev's used to be 2k and stay around 1900k on tickover after it warmed this morning after turning it it rasied to 2.7k on cold and then rested at about 1500k....so the warm idle is lower but the cold Idle is higher!!!!...does this mean the AFM is no good or something else???

jackherer 543 Posted March 20, 2006 its got NOTHING to do with your AFM mate Share this post Link to post Share on other sites
Adam B 0 Posted March 20, 2006 Could be overfuelling due to a dodgy temp sensor. Could be the wiring to the AFM and make sure the throttle butterfly is closing properly. Could be the AFM, but not angle dependant... cheapest option is the wiring and temp sensor Share this post Link to post Share on other sites
jackherer 543 Posted March 20, 2006 overfuelling wont make it rev higher, to do that air has to get in somewhere. Share this post Link to post Share on other sites
